Did you know that we still aren’t sure what causes PMS? We know it’s influenced by fluctuating hormone levels, but it’s not clearly linked to a deficiency or overabundance of any particular hormone. It also appears to be tied to our brain chemistry and our body’s neurotransmitters, which are chemical messengers. Their levels and how our bodies respond to them change throughout our cycles, which can result in changes in your mood, sleep, appetite, and pain, resulting in symptoms of PMS and PMDD, a severe form of PMS. Even with this knowledge, we have yet to find a clear answer for the very important question of what causes #PMS. We’re hoping to see a lot more research on PMS soon. #pmdd #period #periodproblems #womenshealthmatters
